bUI Ihe dirdiiGII oC Ihe ek8rieal fi rr, bcing dilTcrent in

Ihe hook ; lite bmde eh, rgcd Ihro' Ihe coaling \ViII be
diCchuged Ihro' Ihe eoaling; becauCe Ihe fire milI! come
out the Carne way it went In,
6. To prol'e this. take IWO bOlrles Ihat IVere eql:ally
charged thro' the hooks, one in each hand; bling Iheir
hooks near e3ch olher, and no Cpark or Ihock IVill follolV;
becaule eaeh hook is dtfp,.(ed togive fire, and neilher to
receive il. Set one of Ihe bOlrles on glaCs, lake il up
by Ihe !took, and apply ils coaling to Ihe hook of Ihe o·
ther; then Ihere will be an explofion and Ihock, and
bOlh bOllles will be dilcharged. [N D, To eharge a
bOllle commodioufly thro' Ihe coaling: place it on a
glars fland; form a eommllniealion from Ihe prime con·
duélor to the eoating, and another from Ihe hook 10 the
IVall or floor ; w!ten it is charged, remove theIaller como
municalion before you lake hold of Ihe bOlde, olherwife
greal pan of Ihe fire will cfcape by it.]
Wheo Ihe lerms of chargin~ or difthargin~ the phial are
~Ced, il is in eompliance with cuflom, aod for IVan! of
bemr ones; fince there is really no 1110" eleélrical fire in
the phial after what is ealled its chorging than beCore, nor
tejí after its di(chorging. Befides, the phi.1IVill not Cuf·
fer what is eafled a chorging, unleCs as mllch fire can go
out of il one way as is thrown in byanother. A phial
eannot be eharged flanding on wax or elaCs, or hanging
on Ihe prime eonduélor, unleCs aeommunication be forol'
ed belween its coaling and the Aoor. But CuCpend two
or more phials On Ihe prime conduélor, one han,ging lO
the tail of the other, and a wire frum Ihe lan tO the
Roor, an equal number of tllrns of Ihe wheel ",íll eharge
Ihemall equally, and eaeh as llrongly as a fingle one
would have been.
When a boule ís eharged in the common way, its i,,·
jid, and outjid, furCaees fland ready, the one 10 gil'e fire
by the hook, the other tO reeeive it by the eoating: yel
~s the firfl will nOt give OUI. IInleCs the other can at the
fame inflanl receive in; fo neilher will Ihe lamr reeeive
in, unleCs the firfl can at the Came inflant gi,e OUI. When
bOlh can be done al once, it is done with iDcooeeivable
quickocCs and violeoee.
Glafs has within ils Cubllaoce Ihe fame quaotilY of e·
leélrieal fire at all times, aod thal quaotity is very greal
in proponioo tO the mafs of elaCs. Thi, quaolity it ob·
llinately retaios ; and will have oeither more oor Icfs,
though it IVill allow a ehaoge 10 be made io its pam . nd

the Gdes, pro,id.d we throw . n equ, l quantity ioto Ihe
other. Yet wheo the fituali oo of the cleél rie.15re is
thus altered io the glaCs, it IVill not be at rdl, or io its
oaturalllate, till il be reflorcd tO its ori~ioA I equality;
and this reflitutioo eaonol be maJe through the Cubllance
